The utility model discloses a fixture along with the reel axle pivoted cooperatees with fixed positioning cam, keeps tip centre gripping and the supported state with the reel axle when the circular arc section motion around positioning cam, and when being less than the radial bellying of circle through radial dimension, fixture's elastic locating arm opens and loosens the centre gripping to the reel axle to move back a section of thick bamboo mechanism and withdraw from with the epaxial fiber container of reel. The utility model discloses it is rational in infrastructure ingenious, the reliable operation.
Description
Technical Field
The utility model belongs to fireworks machinery, concretely relates to reel shaft's fixing device.
Background
The existing full-automatic firework winding machine adopts a winding drum mandrel, and the procedures of paper winding, cutting and unwinding are completed on the winding drum mandrel. The production period of one firework paper tube is long, the productivity cannot be improved, and the cost cannot be reduced, so that the situation becomes the technical bottleneck of speed increasing of the automatic firework winding machine, and the problem of mass production of firework manufacturing enterprises also becomes. For this reason, an apparatus for performing the winding, cutting and unwinding processes during the rotation using a rotating mechanism having three winding shafts has been proposed to improve the winding efficiency. The reel axle is at the reel, cut a section of thick bamboo process and must support at both ends, must make the one end of reel axle be in the cantilever state again withdrawing a section of thick bamboo process to it withdraws out the reel axle to withdraw a section of thick bamboo mechanism, designs one kind and adapts to this kind of equipment working method, and is rational in infrastructure, and the reliable fixing device of reel axle of operation has important realistic meaning.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a fixing device of adaptable multistation reel equipment rational in infrastructure, the reliable spool of operation exactly as required.
Realize the utility model discloses the technical scheme that the purpose was adopted as follows:
the utility model provides a fixing device of reel, include around the main shaft setting and along with a main shaft pivoted at least reel, establish at fixture that the tip of main shaft tip and reel corresponds, fixed setting with fixture complex positioning cam, the fixture is in when rotating the tip centre gripping of reel or unclamping under positioning cam's the effect.
The clamping mechanism comprises a pair of elastic positioning arms which can swing around a hinge shaft and can be opened and closed, and the front end and the rear end of each elastic positioning arm respectively clamp the end part of the winding drum shaft and are matched with the positioning cam.
The front end and the rear end of the elastic positioning arm are both provided with rollers.
The end part of the main shaft is provided with a shaft end positioning disc, and the clamping mechanism is arranged on the shaft end positioning disc through the hinge shaft.
Advantageous effects
The utility model discloses a fixture along with the reel axle pivoted cooperatees with fixed positioning cam, keeps tip centre gripping and the supported state with the reel axle when the circular arc section motion around positioning cam, and when being less than the radial bellying of circle through radial dimension, fixture's elastic locating arm opens and loosens the centre gripping to the reel axle to move back a section of thick bamboo mechanism and withdraw from with the epaxial fiber container of reel. The utility model discloses it is rational in infrastructure ingenious, the reliable operation.
The technical solution of the present invention will be described in detail with reference to the accompanying drawings.
Drawings
Fig. 1 is an isometric view of the present invention.
Fig. 2 is an axonometric view of a partial structure in the present invention.
Detailed Description
Referring to fig. 1 and 2, the fixing device for the winding drum shaft provided by the utility model comprises a main shaft 1 with a mounting disc 2 at one end, three winding drum shafts 3, 4 and 5 which are arranged on the mounting disc 2 around the main shaft 1 and can rotate, a shaft end positioning disc 8 arranged at the other end of the main shaft 1, a clamping mechanism arranged on the shaft end positioning disc 8 and corresponding to the end parts of the winding drum shafts 3, 4 and 5, and a positioning cam 9 which is fixedly arranged and matched with the clamping mechanism, the clamping mechanism comprises a pair of elastic positioning arms 7 which can swing around a hinge shaft and can be opened and closed, the elastic positioning arms 7 are arranged on a shaft end positioning disc 8 through the hinge shaft, rollers 6 are arranged at the front ends of the elastic positioning arms 7 and are connected with the shaft end positioning disc 8 through springs 12, the front ends of the elastic positioning arms 7 are used for clamping the end parts of the drum shafts 3, 4 and 5, and the rear ends of the elastic positioning arms 7 are matched with a positioning cam 9 through rollers 6'; the main shaft 1 is mounted on the frames 10, 11, and the positioning cam 9 is mounted on the frame 10.
When the paper tube withdrawing mechanism works, a power transmission device (not shown) drives a main shaft 1 to drive the reel shafts 3, 4 and 5 and the clamping mechanism to rotate together, the positioning cam 9 is fixed, the clamping mechanism rotates relative to the positioning cam 9 when rotating along with the main shaft, the position of the rear end of the elastic positioning arm 7 is changed in the matching process of the elastic positioning arm and the positioning cam 9, the front end of the elastic positioning arm 7 keeps the end parts of the reel shafts 3, 4 and 5 in a clamping and supporting state when moving around the arc section of the positioning cam 9, and when the elastic positioning arm 7 passes through a convex part of which the radial size of the positioning cam 9 is smaller than the circular radius, the elastic positioning arm 7 opens and loosens the clamping of the reel shafts 3, 4 and 5, so that the paper tubes on the reel shafts 3, 4 and 5 are withdrawn by the paper. The roller 6 at the front end of the elastic positioning arm 7 can reduce the friction with the reel shafts 3, 4 and 5.
